I am preparing for army so my sister gifted me MI fitbit band. And It is really surprising that Mi 2 band does not support Windows mobile. How and why? The millions of windows users are ignored!
If we talk about features, then it comes with so many features like you can measure your heart rate by cycling to the appropriate pane, MI software automatically calculates distance and burnt calories and those are transferred to the Mi Fit app. And you can enable automatic heart-rate measurements during your sleep. All health data collected by the Mi Band 2 like heart rate measurements, steps, distance, calories, sleep info and activity can also be used by other apps too like pedometer.
Its easy to use and light weight, it look very cool like a digital wrist band.
Battery life is mind blowing as with full charge you can use it for 30 days.
Everything is fine but its not value for money for me as it dosnt support windows phone.
